-lV|USlC-ROLLER FOR MECHANICAL MUSICAL INSTRUMENTS.

SPECIFICATION forming part of Letters Patent No. 308,619, dated December2, 1884.

A pplieation tiled January 5, 1884.

T0 CLZZ whom it may concern.-

Be it known that I, JOHN MAXEIELD, of London, England, haveiuvented acertain new and useful lmprovement in MusieRollers for MechanicalMusical Instruments, of which the following is a specification.

My improvement relates to mechanical musical instruments whereinisemployed a traveling music-sheetfor controlling the speaking of thesoundproducing devices. The traveling music-sheet for such an instrumentis generally wound from one roller to another during the playing of theinstrument. It has been found most convenient to guide the musicsheet inits transit by means of flanges or heads on the rollers; but in shipmentthese flanges or heads have proved very objectionable not only onaccount of their bulk but also It is the object of my invention toprovide a simple and convenient means for connecting flanges or headsand journals to aroller of the kind named, so that they may be readilydetached from the roller when desirable and reattached when needed.

The improvement consists in a novel combination of parts foraccomplishingthis, and in the combination of such parts with bear-. ingsthat will limit the endwise movement of the journals.

In the accompanying drawings, Figure 1 is a sectional side view of a'roller, journals, flanges, or heads and bearings embodying myimprovement. Fig. 2 is a side view of the roller with the middlepartbroken away to economize space, and a side view of flanges or heads andjournals therefor. Fig. 3 is an end view of the roller. Fig. 4 is a viewof the adjacent side or end of the flange or head that fits the end ofthe roller which is shown in Fig. 3, and Fig. 5 is a view of one of thebearings and an end view of one of the roller-journals.

Similar letters of reference designate corresponding parts in all thefigures.

A designates a roller, preferably made of wood and of cylindrical form.In one end it is provided with a cavity, a, in which is fitted ajournal, B. I may make this journal of iron. The cavity a near its outerend has a bushing, 12, of hard wood or other material thatwill (Nomodel.)

- not readily wear away. When made of hard wood this bushing may, ifnecessary, be secured in place by glue or other adhesive substance; butit may, when made of any mate rial, be merely driven in. At the outerend the cavity a opens into a larger cavity, 0, that extends to theextreme end of the roller.

0 designates a flange or head which may be made of wood, but preferablywill be made of binders board orleather-board. as such material is lightand cheap and will not split off like wood. This flange or head isprovided with a hub, C, which has a flange, G at the outer end, and ismade sufficiently small at the inner end to be capable of fitting in thecavity 0. This hub may advantageously be made of wood. The flange orhead will preferably be secured to it by glue or otherwise, and thejournal 13 is fixedly secured to it by being driven in, or in any othersuitable manner. This journal extends beyond each end of the hub. Thejournal, hub, and flange or head are secured together as one structure,and the inner ends of the journal and hub are made of such sizesrelatively to the sizes of the cavities a and 0, respectively, that theymay be inserted into and removed from the same at pleasure, and wheninserted will be held by friction.

D designates another journal, which I may make of iron. It is fittedinto a cavity, d, in the roller. This cavity (Z is preferably fittedwith a bushing, e, of hard wood or other durable material. Such bushingmay be secured in .place in the same manner as the bushing b.

The journal D has aflixed to it ahub, E,whicl1 preferably will be madeof wood. Onto this hub is fitted a flange or head, F, which I prefer tomake of such material as I have mentioned as applicable to theconstruction of the flange or head 0. This flange or head F ispreferably secured byv glue or otherwise to the hub E.

On the hub E is affixed a pulley, Gr, made, as here shown, of threepieces of wood. These three pieces of wood will have the grain re versedto obviate splitting, and will be glued together and secured to the hubE by glue or otherwise. The journal D extends beyond the hub E at bothends. This journal D, the hub E, and the flange or head F form in effectone structure. The pulley G is used for the transmission of motion tothe roller. A pin, f, extending from the inner end of the hub E, entersa hole, g, in the adjacent end of the roller when the journal D isinserted in the cavity (1, and locks this journal and the rollertogether, so'that when the journal is rotated through the agency of thepulley G the roller will turn also. This journal D and the pin f can,however, easily be withdrawn from the roller when desirable. It will beseen that the j ournals and flanges or heads are detachable from theroller at will.

H designates bearings in which the journals B D are fitted andsupported. They consist, as here shown, of blocks fitted with springs h,into and out of which the journals may be moved in directions transverseto their axes. These bearings are so arranged that they will prevent thejournals from becoming detached from the roller even if they had anytendency to do so.

It will be seen that by my improvement I produce a roller which can haveheads or flanges and journals readily attached when the roller is to beused, and detached when the roller is to be transported or put away. Theroller will take up much less room and will be very much lighter whenits heads or flanges are detached.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with a roller, of hubs, i

one of which enters said roller, journals permanently attached to thehubs and entering through and beyond the hubs at both ends, and theirinner ends fitting in cavities of the roller beyond the inner ends ofthe hubs, and detachable heads or flanges upon said hubs, the hubs, thejournals to which they are respectively connected and the said heads orflanges being capable of being together detached from said roller andreattached, and when attached to be held by friction in said roller,substantially as specified.

2. The combination, with the roller A, provided with the cavities a c,of-the journal B,

to said journals, detachable heads or flanges O and F on said hubs, andbearings H, provided with springs h, substantially as specified.
